I traced it back and found where it was being allocated. That segment of code
where it was allocated did no point it to NULL in case it didnt need to be
allocated. Long story short it was trying to free a pointer that had
"something" but its location was unknown so not even a precheck like
if(
Do you know the function allocated the char* on the heap, and that it expects
your code to free it?

Subj: Memory Manager Error
Date: Tue Nov 25, 2008 4:20 pm
Size: 366
I acquire a Char * from a function and then at the end of my application I free
the pointer by doing a MemPtrFree(p). I then proceed to point p=NULL; and this
causes an error "MemoryMgr.c, Line:3760, Invalid chunk ptr" Any ideas?

I have no idea. But I'm not sure this is the point: from the programme
ns it may not be interfering
with the memory management information .
Anyways , thanks again & regards ,

My guess is that your application trashes the heap. You probably overwrite
some memory management information, whi
should be done ..
Thanks ,

I think that it checks if the address are valid and inside the perimiter of
the dynamic heap.
I'll hope you solve this problem. Good Luck !!!

Hi Dhanashri,
I don't think that there should be any limitation, but you have to make sure
that if you have defined a buffer that can hold 32k and you just have 22k in
i you shouldn't try to move 32k. DmWrite should you use when you don't have
your buffers in the dynamic heap and I think that MemM
alm os 5.0 applications & their possible causes ?

Make sure that you don't trying to move more bytes then the buffer holds.
You have to be sure that you move the right size from the source buffer.

Hi Dhanashri,
Use the debugger to see if you get any data in your local buffer and if you
get the right address before you use the function MemMove. I don't see why
MemMove shouldn't work either so check the values in your buffer and the
pointer you use for each buffer.

It sounds like you get a pointer that has a NULL-address. Do you use any
memory allocation function eg. MemPtrNew, MemHandleNew or MemGluePtrNew ?
